Given numbers are 660, 390, 930, 625

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(660, 390) = 8580

GCD(660, 390) = ( 660 x 390 ) / 8580

= 660 / 390

= 660

Step2:

LCM(30, 930) = 930

GCD(30, 930) = ( 30 x 930 ) / 930

= 30 / 930

= 30

Step3:

LCM(30, 625) = 3750

GCD(30, 625) = ( 30 x 625 ) / 3750

= 30 / 625

= 30

So, Greatest Common Divisor of 660, 390, 930, 625 is 5
